seek-h262 is a portable MPEG decoder.
setBfree DSP tonewheel organ is b3 emulation based on the code of Fredrik Kilander's Beatrix organ emulator.
slack1f42 is a collection of command line utilities for reading and editing 1f42 H262 maps. 1f42 H262 maps are H262 (or MPEG) stream descriptions containing information such as stream frame rate, stream duration and number of frames, file position of stream frames, and so forth. 1f42 audio stream maps can be used by the Mylene1f4 audio player in performing fast and accurate random access on MPEG audio streams.
SvOlli's Little Audio Related Thingies, or SLART for short, is a compilation of rather simple programs that are related to audio files: it consists of a player (Partyman), a CD ripper, a tag editor, a downloader for music files that also works with MySpace, and some other tools.

stereoboost widens, enlarges, and boosts the stereo effects in music. It does this by extracting the stereo signal from music, multiplying this by a factor, and then mixing it back into the audio file with the original mono signal.
SuperShow is a program to create Adobe Flash files from some slides and an audio or video file. SuperShow allows you to easily synchronize the audio and the slide transitions and insulates you from the command-line interface of creating Flash files with SWFtools.
Swac Tools is a set of programs that allows you to get the most of the words audio collections (SWAC) that are provided by the Shtooka Project. At the moment, there are two programs: swac-get, which enables the loading into a SQLite3 database of audio collections, and swac-explore, which allows you to browse the database and listen to audio files.
Tiny Ear Trainer
Tiny Ear Trainer is a tiny piece of software that helps you to recognize musical intervals by associating them with colors.
trx is a simple toolset for broadcasting live audio from Linux. It sends and receives encoded audio over IP networks, via a soundcard or audio interface.
tsdecrypt reads decrypts incoming mpeg transport stream over UDP/RTP and then decrypts it using libdvbcsa and keys obtained from OSCAM or similar CAM server.
TTtrigger is a program intended for theater use. It uses JACK to trigger sound effects and other sounds to predefined audio ports. A shortcut key can be assigned to each sound effect or you can trigger the sounds sequentially.
WAVE Utilities is a set of three programs for dealing with WAVE format audio files. Some software is unable to parse complex WAVE files containing such things as playlists and padding. SimplifyWave converts complex files into files that such programs can read by stripping everything other than the data chunk. RepairWave inserts the required data chunk id and size information into ill-formed files in which the audio data directly follows the header. InfoWave extracts information from a RIFF/WAV or RIFX/WAV file and reports on the contents of the file.
X11 Audio Extension
The X11 Audio Extension aims to provide audio support for the X Window System, in particular the X.Org reference implementation. Audio data can be directly routed through the X protocol so that remote applications can transparently play and capture audio across the network in the same way they can do graphics and mouse/keyboard user interaction. Applications with strict latency requirements can alternatively use shared memory. The extension provides hooks for an "audio compositing manager" that manages how multiple applications may simultaneously access the audio hardware (mix streams, mute some streams); it is the counterpart to the window manager.
